We spend a lot of time, money, and effort on keeping our computers, bank accounts and even our phones from being hacked by malicious actors. But this week on "Aim Higher," I talk to my good friend Kary Oberbrunner about a type of hacking that's even more important and more insidious: the hacking of our brains. A computer hack is simply "unauthorized access" to your systems. Have you asked yourself, though, "To whom and what do I give access to my thoughts and attention?" Are you deliberate and careful about that? Kary's new book, "Unhackable" provides a great blueprint for taking back your attention and intentions and creating a mindset for success. Listen in as we discuss this important topic.
